In an integrated-services cable network, three major types of video services: broadcast service, real-time video service and delayable video service are offered, each type of services has different blocking probability requirement. Given a limited number of channels, the channel assignment problem is to determine the channels' allocation for the dynamic service requests so that (1) the network throughput is maximized, (2) the blocking probabilities of each type of services are minimized (3) the fairness criterion is satisfied. In this paper, a dynamic channel sharing strategy using fuzzy set theory is proposed. Based on the fuzzy controller, four different strategies are introduced to solve the channel assignment problem. Simulation results show that some proposed strategies obtain high network performance, high fairness as well as the acceptable blocking probability.
